2026 Singapore Diamond Guide
Top Diamond Jewelry Trends Singaporeans Are Buying in 2026
If you look at the engagement rings Singapore market in 2026, one thing is absolutely
clear: the era of the "whisper-thin" band and the cookie-cutter design is over. Today, couples in
Singapore are looking for character, durability, and a genuine story. Whether you are upgrading an
heirloom or stepping into the boutique for your very first diamond ring Singapore, the
aesthetic has shifted toward bold metalwork, vintage soul, and undeniable presence.
Here are the top 5 trends dominating our bespoke requests this year.
1. The Mega-Trend: The Oval Dominance and the Marquise Runner-Up
When it comes to center stones, elongated shapes are ruling the market because they maximize finger
coverage and offer incredible visual value.
- The Oval Takeover: Right now, a staggering 60% of our clients are buying oval engagement rings. It is a certified mega-trend that delivers the intense sparkle of a round brilliant but with a highly flattering, finger-lengthening silhouette.
- The Chic Alternative: The marquise cut is on a serious rise and is the definitive runner-up. We personally love the marquise because it is super chic, elegant, and the best cuts are absolutely full of light and life. Because of their stretched shape, they offer the nicest deals for a massive surface area, giving you maximum visual impact.
2. Substantial Settings: The End of "Delicate"
The market has pivoted aggressively toward thick band engagement rings.
- The Aesthetic: Heavy 18k yellow gold "cigar bands" are replacing 1mm wires. This chunky aesthetic perfectly captures the "Quiet Luxury" vibe that is highly sought after in Singapore right now.
- The Function: Beyond looking incredibly confident, a thick band provides necessary structural durability and support for the larger carat weights clients are purchasing today.
3. Architectural Metalwork: Bezels & East-West
How the stone is mounted is changing just as much as the stone itself.
- The Bezel Setting: Instead of delicate prongs, the diamond is fully encased in a sleek rim of gold. It is incredibly secure for active lifestyles and looks highly architectural.
- The East-West Twist: Setting an elongated stone (like an oval or marquise) horizontally across the finger. It is an edgy, modern twist that makes a classic shape look entirely bespoke.
4. Antique Cuts: The Return of "Soul"
There is a massive pushback against mass-produced, laser-perfect stones. Buyers want diamonds that feel
like they have a history.
- We are seeing a major spike in requests for Old Mine cut diamonds. Hand-cut primarily in the 18th and 19th centuries, these stones feature high crowns, chunky facets, and a warm, romantic internal glow rather than a splintery, modern sparkle. No two antique stones are exactly alike, making them the ultimate flex for a truly unique piece.
5. Reimagined Three-Stone Rings
The classic three-stone ring is getting a contemporary update. Instead of three matching round
diamonds, modern designs are flanking a central Oval or Cushion cut with distinct, unexpected
step-cuts like crisp Emeralds, Baguettes, or edgy Trillions (triangles).
The Non-Negotiable: True Certification
With vintage cuts and unique shapes taking center stage, the technical quality of the stone is more important than ever. Whether it is a flawless marquise or a soulful antique cut, savvy buyers strictly demand GIA certified diamonds. A GIA report is the only way to truly verify the cut quality, color, and intrinsic value of these high-demand stones, ensuring your investment is secure.

Tal Wilf: The Visionary
"Right now, 60% of our clients are buying ovals—it's a mega-trend. But keep your eye on the marquise. We personally love them because they are super chic, elegant, and offer the absolute best deals for maximizing surface area. Whether you choose the trendy oval, the elegant marquise, or a chunky Old Mine cut, you must be strict about the pedigree. That is why we only deal in GIA certified diamonds." -
Elad: The Market Strategist (Singapore)
"Walking through the CBD, the shift is obvious. The standard diamond ring Singapore used to be a safe, delicate round brilliant. Now, my clients want heavy 18k yellow gold thick band engagement rings. It shows immense confidence. They want a piece that feels substantial on the hand and stands out in a boardroom." -
Gilad: The Pragmatic Analyst
"Let’s talk logistics. Sourcing a top-tier marquise without a dark 'bow-tie' effect, or finding genuine Old Mine cut diamonds, requires deep expertise. You are hunting for rarities, not ordering from a catalog. We leverage our global network to secure the absolute best stones before they disappear into private collections. It’s a hunt, but the payoff is a ring that cannot be duplicated."
